Be itlniown tha'tl, Reim-IARD W'. a citizen of the'.United Statesyresiding'at Davenport, in they county o'`SCott, in thea `State oflovva, have invented a neiv and useiiul lniproveinentin.Spring Tires, ot Awhich.

the following is a specification. i i 1 ble. i y p i side elevationlof the liey bolt..`

with 'each other in use. `Theivindings of coil spring" 4t are directioiied opposite to the 'windings of `Coil.spring 3,`the ends voitcoil 'tary portion ot the outer spring'.`

My invention relatesto improvements iu spring tires for vehicles in which coil springs are circularly mounted `upon the `metal itini of al vehicle either .enclosedly Withina casing' or uncovered and the objects of inyinvention are', to provide` a resilient vtire orvehlcles Without the useof airg at the'saine-tiine elastic, durable and yotfnietal, yet having'. strength and synfini'etry of form; also'yca-U' pable ot effectual responsive adaptationfto light and heavy loads under varying road conditions; also to provide a lniea'ns of se?,

curing the` coil 'springs upon the metal rim .of a vehicle;` also to provide' spring tires adaptable r.to use naked or Within a casing, and to provide a spring' tire composed of coil springs, one `Within the other, in such nianner as to constitute a noieeless tire, and to provide means of securingjthe coil springs upon `the riin, and of tightening the saine to any` desired tension.` y f Other objects Will be apparent from the descriptiono' theniechanisin adapted.

attain these objects by the mechanism illustrated `in the yaccoi'npanying' drawings,
